Bubbles in Eternal Inflation: A Classic(al) Effect
Speaker(s): John Giblin
Abstract: Cosmological bubble collisions arising from first order phase transitions are a generic consequence of the Eternal Inflation scenario. I will present our computational strategy for generating and evolving these bubbles in 3+1 dimensions and in a self-consistently expanding background. I will show th... read more

Gravitational radiation from the decay of primordial black holes
Speaker(s): John Giblin
Abstract: If primordial black holes are produced at the end of inflation, they should quickly decay via Hawking radiation. For the most part the radiation signature of these black holes will be wiped out, as the universe is still radiation dominated when they disappear. The exception to this would be a stocha... read more

Gravitational Radiation from Preheating
Speaker(s): John Giblin
Abstract: Parametric resonance, also known as preheating, is a plausible mechanism for bringing about the transition between the inflationary phase and a hot, radiation dominated universe. This epoch results in the rapid production of heavy particles far from thermal equilibrium and has the potential to sourc... read more
